The "Ocean's Eleven" star, who is currently in Germany preparing to shoot the new movie "The Monuments Men," had been enjoying a meal at the Grill Royal on Friday when he discreetly picked up a stranger's $134.66 check.

Shocked by the generous gesture, the unidentified patron left his business card at the actor's table in the hopes of one day being able to return the favor -- only to later realize the man was Hollywood star Clooney.
